“After the release, some bulls turned to that old reliable excuse – bad seasonals. According to one analysis making the rounds, had the BLS used last year's factor – computed, of course, using exactly the same concurrent technique as this year's factor – the gain would have been 221,000! (Whoever did this made a mistake by comparing the NSA and SA levels for the two months – you have to compare the over-the-month changes.) Still, if you're going to play this game, you should be consistent, and apply last year's seasonals to several months, not just one. If you do that, May's gain of 25,000 would turn into a loss of 19,000, and June's gain would be a mere 73,000, all total payrolls. In any case, why should you do that? The seasonals are recomputed every month based on recent experience and calendar quirks, and should be more aggressive in a recovery. (Hope we won't be using the trend set in the depth of the recession as the bar going forward.) Also, there is no adjustment to the headline number – the sectors are adjusted separately (96 different industries at the 3-digit NAICS level, to be precise) and the total is the sum of those components. The whole argument is bogus.”
